It's the bad craftsman/woman who blames his/her tools; but, thanks to the efforts of John Lithium, we have just the tool for the job.
The Lithium Toolbox is a series of soundscape tools - sound concepts - that have been offered up for free to the world at large, for subversion and subduction. A collection of "nightmares, dreams, hallucinations and worst-case scenarios" to use in your own sonic adventures.

Worst-Case Scenarios is a collection of noise, dark ambient and experimental soundscapes created using the Lithium Toolbox. Each track contains at least one of the samples provided in the Toolbox; which has been manipulated to create the sounds you hear. The artists contributing were given but a single objective: Use and abuse. Subvert and conquer. Submit and acquiesce. Return to the master that which he desires. Give him your Worst-Case Scenario.
